7f98bdf040 readclock: code clean-up, add -q, manpage updates
- Simplify the message passing between readclock and the driver.

 - Add a -q command line option to suppress warning messages. This
 cuts down on the noise when readclock is called early in the boot
 sequence and a secondary RTC driver (ex TPS95650) isn't up yet.

 - Update the man page to be less i386 centric and add details about
 the new -q option.

09db2a8c67 readclock: add support for am335x RTC
Add support for getting/setting the am335x SoC's internal real
time clock. Also, allow the power off alarm to be set.

Make readclock an "always on" driver. This is needed for setting
power-off alarms whenever the power button is pressed on the BBB.

Replace the readclock.sh script & single run driver with a
readclock program that takes the same arguments and forwards
the requests on to the always up readclock driver.

5acaa0814f kernel, ramdisk: some boot unification
To use the new SD building script, Linux has to be configured with
loop.max_part=15 on the command line (or set at module load time)
to make the loopback device see the partitions.

This commit removes a lot of differences between the ARM and x86
boot ramdisk and rc scripts. It changes the ARM build from running
from ramdisk to requiring a full filesystem on the SD image and
booting into it.

	. ramdisk: remove some arm-only utilities only used for running
	  from the shell
	. remove ARM-only rc.arm, proto.arm.small, ttys and mylogin.sh
	  boot-time ramdisk files
	. change kernel to add "arch" variable so userland knows what
	  we're running on from sysenv
	. make ARM use the regular ramdisk rc file, changed to distinguish
	  i386-only and ARM-only drivers; requires rootdevname to be set
	. change /etc/rc and /usr/etc/rc to start i386-only drivers only on
	  i386 systems
	. change the kernel/arm to have a special case for the memory
	  driver to load it higher so it can be bigger
	. add uEnv.txt, cmdline.txt and a for now highly linux-dependent
	  SD preparation script arm_sdimage.sh to the git repository in
	  releasetools/

ed1af3c86c VM: full munmap
complete munmap implementation; single-page references made
a general munmap() implementation possible to write cleanly.

	. memory: let the MIOCRAMSIZE ioctl set the imgrd device
	  size (but only to 0)
	. let the ramdisk command set sizes to 0
	. use this command to set /dev/imgrd to 0 after mounting /usr
	  in /etc/rc, so the boot time ramdisk is freed (about 4MB
	  currently)

c4d9681327 Add entry in fstab and let the mount system call start devman.

the /sys file system (see docs/UPDATING).

6759b24c57 /etc/rc: use mount -a instead of manual parsing
The rc script manually parses /etc/fstab to mount all file systems.
To do that it needs /bin/sed which does not exist anymore. mount(8)
now supports the -a flag which causes it to mount all file systems
listed in /etc/fstab except for '/'. File systems marked with 'noauto'
are skipped.

7750657783 Add hot plugging infrastructure in rc file.
Adding hot plugging infrastructure in rc file. This includes
starting the devman service, mounting it's file system and
starting the corresponding devmand daemon.

This patch also provide error free shutdown of the USB sub-system.

The USB sub system needs to be shutdown in a certain order but also
consists of components living in /usr/pkg/. By checking the
existence of usbd we can stop it in the correct order.

cedeabb357 mainstream-format fstab format
. detect both formats in /etc/rc
	. generate new format in setup
	. obsoletes /etc/fstab.local: everything can go in /etc/fstab
	. put shutdown/reboot/halt and a copy of /usr/adm/wtmp
	  (/etc/wtmp) on root FS so that we can do shutdown checks before
	  mounting /usr
	. new fstab format makes getfsent() and friends work

b47483433c Added a hack to start binaries from the boot image only. In particular, setting
bin_img=1 in the boot monitor will make sure that during the boot procedure the
mfs binary that is part of the boot image is the only binary that is used to
mount partitions. This is useful when for some reason the mfs binary on disk 
malfunctions, rendering Minix unable to boot. By setting bin_img=1, the binary
on disk is ignored and the binary in the boot image is used instead.

- 'service' now accepts an additional flag -r. -r implies -c. -r instructs RS
  to first look in memory if the binary has already been copied to memory and
  execute that version, instead of loading the binary from disk. For example,
  the first time a MFS is being started it is copied (-c) to memory and
  executed from there. The second time MFS is being started this way, RS will
  look in memory for a previously copied MFS binary and reuse it if it exists.
- The mount and newroot commands now accept an additional flag -i, which
  instructs them to set the MS_REUSE flag in the mount flags.
- The mount system call now supports the MS_REUSE flag and invokes 'service'
  with the -r flag when MS_REUSE is set.
- /etc/rc and the rc script that's included in the boot image check for the
  existence of the bin_img flag in the boot monitor, and invoke mount and 
  newroot with the -i flag accordingly.

f47aa04a30 . removed readclock command and cmos driver.
. replaced by a readclock 'driver' that runs once, a re-imported version
  of the minix 2.0.4 readclock command.
. this has also restored cmos writing.
. readclock wrapper script calls service command to run /bin/readclock.drv
  once.
